To Vista or not to Vista; is that really the question? With Microsoft’s long-awaited operating-system upgrade, well … upon us … it might be time to consider alternatives. Apple’s fine Unix-based OS X is certainly an option, but if you’re balking at investing in the new hardware you’ll need to support Microsoft’s new graphically seductive, resource-gobbling OS, do you really want to replace all your Windows machines with Macs?

Maybe it’s time to consider Linux — or rather a Linux. There are more than a few flavors of this Unix-like open-source operating system in circulation these days (about 300, by one count). One of the commercially backed Linux distributions, Ubuntu, has become something of a darling of the OSS crowd, and it’s well worth a look. There’s a lot to like in the latest version of Ubuntu — and a few things to watch out for from an enterprise perspective.
